Step-by-Step Guide

1. Prepare the Top-Floor Bedroom: Start by focusing on the top-floor bedroom. Position the wooden bed frame against the center of the back wall, slightly left of the roof’s peak. Arrange the pink duvet and floral pillow on the bed to align perfectly with the frame edges. Center the scalloped-edge rug beneath the bed, ensuring it matches the floor grid.
2. Place the Nightstand and Accent Pieces: Add the bedside decor by selecting the small wooden nightstand with its yellow cloth drape, placing it to the left of the bed. Carefully align two delicate white items - a tall cylindrical candle and a smaller decorative box - on the nightstand. Add the pink mushroom-shaped lamp on the front-right corner of the nightstand.
3. Hang Wall Art, Planter, Shelf, and Curtains: Focus on the back wall accents by hanging twin picture frames — one oval portrait and one rectangular green-leaf print — side by side above the nightstand. Install the hanging planter left of the frames and yellow drapery panels on the right-side windows, using red sashes.
4. Arrange the Cozy Seating and Tea Table: Transition to the middle floor by adding seating and a tea station. Place the plush pink round armchair mid-floor. Position the white circular coffee table in front, adding a pastel green teapot, matching cups, and a watermelon-slice plate. Finally, include an orange flower-shaped floor cushion beneath the table.
5. Set Up the Sofa, Fish Pillow, and Sunflower: Continue decorating with a red upholstered sofa against the right wall. Attach an orange fish-shaped pillow to the center of the sofa, and set a sunflower in a terracotta pot on the floor to the left of the sofa.
6. Position the Piano and Stool: Add musical charm by placing the upright piano in the right corner. Align the brown piano against the rightmost wall, slightly overlapping the yellow star-patterned cloth with the windowsill. Place the small round piano stool in front of the piano keys.
7. Install the Kitchen Counter and Cookware: Add the lower middle floor kitchen elements by placing the main countertop unit against the back wall. Align the sink to the left and the stovetop to the right. Add a cooking pot and a frying pan with an egg on the burners.
8. Create the Art Corner: Setup the painting area by placing a wooden easel adjacent to the right window. Mount a vibrant sunflower canvas onto it, position a paintbrush holder to the left, and place an open palette tray in front.
9. Add the Green Armchair and Throw: Personalize the studio space with a plush green armchair near the kitchen area. Drape a soft yellow throw over the chair's top left arm. Place a small paw-print rug in front of the chair.
10. Install the Curved Slide: Enhance connectivity by adding a green S-shaped slide to the middle floor's left edge. Ensure the slide curves downward, aligning the bottom exit above the pool's center.
11. Position the Pool, Ladder, and Floats: Create the pool area by adding the kidney-shaped pool tile piece below the slide exit. Position a small ladder on the pool's right side, a pink flamingo float on the left, and a bear figure with yellow goggles near the ladder.
12. Landscape the Garden and Path: Complete the level by arranging garden details and a stone walkway. Place white picket fence panels along the room edges, add floral decorative arch panels, plant shrubs and colorful flowers, and lay gray stepping stones in a path through the garden.
